What is a person called if they are under the legal age to contract?

A person who is under the legal age to contract is referred to as a minor. In legal terms, a minor is defined as an individual who has not yet reached the age of majority, which is typically 18 years old in most jurisdictions. Minors have limited legal capacity to enter into binding contracts. This means that contracts entered into by minors are usually voidable at the minor's discretion, providing them with the opportunity to disaffirm the contract. The legal principles surrounding minors and contracts exist to protect young individuals from being taken advantage of due to their lack of experience and understanding of complex legal matters.

The other terms presented are defined differently within legal contexts. An agent is someone authorized to act on behalf of another person, typically called the principal. A principal refers to the person who grants authority to an agent to act for them. A ward is a minor or someone under the care of a guardian, who has been legally placed under the protection of the court. While all these terms are related to legal categorizations, the specific designation for a person under the legal age to contract is a minor.
